Description Matthias Clasen 2009-02-17 19:03:02 UTC

I assume this is a side-effect of the flat volumes that recently landed in rawhide.

I am playing music in rhythmbox, open the popup in the gvc-applet, adjust the volume, click on desktop background to dismiss the popup. Afer a very short moment, the icon changes to muted, and opening the popup again and changing it does not bring any sound back.

Opening the sound capplet shows all output volumes (ie the master slider, the event sound slider and the rhythmbox volume) at 0.

Comment 1 Bastien Nocera 2009-02-17 19:05:17 UTC

Does this happen with anything but rhythmbox? My guess is a dupe of bug 485547

Comment 2 Matthias Clasen 2009-02-18 07:58:20 UTC

Also happens with flash

Comment 3 Matthias Clasen 2009-03-02 03:27:16 UTC

Still happening here.

Same thing happens with audacious, although the audicious volume control isn't moved by either the gnome applet or pavucontrol.  Sound still gets muted after sliding the gnome-applet then touching anywhere else on the desktop.

Bastien, 

commenting out the following lines in 
gvc-channel-bar.c:on_scale_button_release_event
seems to fix this for me. Can you explain those lines ? 
For me, they seem to have the effect of always injecting a value of zero
into adjustment at the end of a drag...

        value = gtk_adjustment_get_value (bar->priv->zero_adjustment);
        gtk_adjustment_set_value (bar->priv->adjustment, value);

Comment 7 Bastien Nocera 2009-03-11 11:27:59 UTC

Probably because I didn't understand what the zero_adjustment was for, and I just copied the code out of on_zero_adjustment_value_changed().

See the patch as reviewed in:
http://bugzilla.gnome.org/show_bug.cgi?id=564313

I guess the zero_adjustment was supposed to be to cache the volume before we were muted. I'll try and fix that.

Fixed in gnome-media-2.25.92-3.fc11
